Why Our Dental Team Decided On Dentistry Without Amalgam
With advanced technologies of dental adhesion, resins and state-of-the-art ceramics, the latest bonded restorations will be close to rivaling nature in strength, comfort, performance and appearance. You can see side-by-side examples in the photo to the left of bonded white fillings vs. metal amalgam fillings. With these innovative materials, it is possible to bond your teeth back together, virtually restoring them back to their virgin strength without the invasiveness of complete-coverage crowns. In most instances, metal fillings may be replaced by materials that are known to be safer than mercury/silver amalgam fillings. It can be, therefore, possible to maintain the healthy, remaining tooth structure, instead of grinding it down for a crown.
Almost everything wears out, and your silver fillings will not be any different. They hold up against tense and significant biting forces each day, and as they get older, they break, leak and can bring about damaging fractures on the teeth. With time, metal amalgam fillings have the ability to absorb water, causing them to swell and even break free from the teeth. When this happens, your tooth is far more prone to decay and tenderness.
Mercury/Silver fillings have some other important detractions that need to be thought of when it is time for you to swap your restorations:
• Silver fillings are much less esthetic than natural-colored fillings. Think about it, they don’t look anything like real teeth.
• Amalgam expands and shrinks whenever subjected to cold and hot extremes in your mouth. The constant growth and contraction with temperature can easily set off cracks as well as fractures in teeth. There may not be any kind of indicators for a while, yet these teeth could become hypersensitive as the fracture increases or opens whenever you bite down or chew food. It is not unusual for patients to come in wanting to know how they broke their own tooth when they had been eating something soft similar to bread or a banana. What they don’t realize is that the tooth almost certainly had a fracture in it well before it eventually came apart.
• Silver fillings under frequent chewing stress are prone to metal fatigue or flexing and bending failure, a concept that can be grasped and demonstrated by repeatedly bending a metal paperclip until it finally breaks.
• Metal fillings are harder and far less flexible compared to the teeth they are molded into. The longer they are in the teeth, the greater pressure they put on the rest of the weak walls of the tooth leading to fractures and cracks.
• Metal fillings are not glued to the cavity. They only sit in the tooth and act under pressure to wedge the tooth apart, like a metal wedge is used to split logs for firewood.
• A minute gap around the filling edge exists as soon as the silver filling is plugged into the tooth; and in this space, continuous leakage and corrosion takes place. This unnoticeable gap is large enough to allow bacteria and food particles to enter in over time and cause decay at the joint between the tooth and the filling. Composite fillings, however, are actually bonded to the tooth preparation area and seal the borders closed from invading bacteria.
• In order to prepare a tooth for a composite filling, the tooth can usually be treated a great deal more gently and with less healthy tooth structure needing to be removed. And thus, the dentist can retain the maximum level of healthy tooth structure as is possible
• Silver fillings necessitate drilling undercuts (think carving out a pumpkin) along with removing more substantial healthy portions out from the tooth to be able to keep the mercury amalgam repair from falling out since it is not attached right to the tooth. Those undercuts might also compromise the tooth as fillings get more substantial and relegate that tooth to upcoming fracture down the road. These cracks might be significant leading to crowning the tooth to repair it or even catastrophic cracks leading to extraction of the tooth.
• Composites, with their opportunity to be conservative and applying their gluelike characteristics, could strengthen and guard against fracture. By intercepting the opportunity for fracturing before experiencing the signs and symptoms of hot and cold sensitivity and biting discomfort, new conservative treatments including natural-colored restorations or porcelain-bonded restorations are actually preventing the negative effects of toothaches and damaged teeth.
• Finally, in many dentists’ opinions, bonded natural-colored restoratives are likely to be safer compared to classic fillings, simply because they do not have any mercury. While the American Dental Association (ADA) suggests the utilization of mercury in metal fillings is safe, there is an ongoing discussion inside the dental sector regarding the unwanted effects of these mercury amalgam fillings. Several of the European countries actually banned the utilization of mercury amalgam fillings to avoid any kind of dangers related to mercury.
Utilizing a PROACTIVE in place of a REACTIVE method to amalgam extraction is actually a choice a lot of patients hope to have us follow.
